Thanks for posting a link to us (Cambridge wood works. We collect around 40 tonnes of wood and timber waste every month and aim to reuse 20% the rest being recycled. We're always happy to meet anyone interested in working with affordable reclaimed timber. We wear rigger boots, not jackboots...
I've just done my floors using ronseal trade wax oil satin finish. Does not yellow like varnish, touch dry in 20 mins and light traffic after 2 hours. At least 2 coats needed after finishing with floor sander at 120g. The best finish I've ever achieved!
